Oh right, I wasn't sure what the pattern was. It does warn about int_t
types in _some_function declarations, but on closer inspection, it only
seems to do so when there is a line break before the parameter
declaration. For example:
CHECK: Prefer kernel type 'u16' over 'uint16_t'
#519: FILE: drivers/staging/comedi/drivers/s626.c:519:
+ uint16_t chan, int16_t dacdata)
